APPARATUS FOR REMOVING LYE, FROM FABRICS.

Specification of Letters Patent.

Patented Sept. 14, 1909.

Application filed October 28, 1907. Serial No. 399,585.

To all whom it may concern;

Be it known that I, OTTO VENTER, a subject of the German Emperor, andresiding at Chemnitz, in the Kingdom of Saxony, Empire of Germany, haveinvented certain new and useful Improvements in Apparatus for RemovingLye from Fabrics Saturated with Soda-Lye, of which the following is thespecification.

This invention relates to an apparatus for removing lye from fabrics,which have been saturated with soda-lye, for the purpose ofmercerization.

One embodiment of my invention is represented by way of example in theannexed drawings, in which: 7

Figure 1 is a vertical cross section through the apparatus on the lineA.B of Fig. 2; Fig. 2 is a plan view showing the steam pipes, and Fig. 3a vertical longitudinal section through the apparatus; Fig. 4 showspartially in side elevation and partially in longitudinal section a pairof mangling rollers in combination with the carrier, and Fig. 5 a planof the same; Fig. 6 shows on a smaller scale a side elevation of theapparatus in combination with the stretching frame of the mercerizationmachine, and Fig. 7 a plan of the same; Fig. 8 shows 011 a larger scalea horizontal section, and Fig. 9 a cross section through the steamjets;Fig. 10 shows on a larger scale a part of the chain which stretches thefabric in its breadth, whereas Fig. 11 shows also on a larger scale aside elevation of one link of the chain and a cross section through theguide for the chain.

As is clearly shown in the drawings, 1 is a closable box, through whichthe fabric- 2 saturated with lye is passed in the direction of the arrowshown in the drawing. As clearly shown in Fig. 3 two girders 3, 4 arearranged at the sides of the box, on which girders the cross-beam 5rests. On each of the latter two slides 6, 7 formed as bearing standardsare supported, seats to becapable of being shifted and secured, saidslides serving to support the lower mangling rollers 8. For this purposethe slides 6 and also the slides 7 are each provided with three rollers9, 10, 11 by means of which each of the lower mangling rollers issupported securely at both ends.

For the purpose of supplying the steam, steam pipes 12, 13 are providedat the two sides of the box 1, from which pipes the transverse pipes 14extend through the uppipes 14 at the same time serve as guides for theslides 15, 16; the latter are also arranged so as to be capable of beingdisplaced and secured, and are each provided with two guide-rollers 19,20 for the purpose of supporting the upper mangling rollers 18. Theupper mangling rollers 18 consequently press by means of their ownweight on the lower mangling rollers 8 and are prevented from movinglaterally out of position by means of the rollers 19, 20. As shown inFig. 3, the pipes 21 branch off from the steam pipe 12, the branch pipes23 being connected with said pipes 21. The branch pipes 23 terminate inthe perforated steam-jet pipes 24, 25 through which the steam isdirected against the back surface of the fabric 2 as clearly shown inFig. 1. The steam pipes 14 are connected through the connecting pipes 26with the perforated steam-je -pipes 27, 28, which serve to direct thesteam against the upper or front surface of the fabric. The steam pipes27 may be suitably varied in length by drawing out or pushing in theparts 30, 31, shown in Fig. 8.

The walls 80, 81 of the box are provided with slots 82. In the slots 82two girders 35 are disposed parallel to each other. The

irders 35 may be shifted in the direction of the arrows 83, 84 (Fig. 2and Fig. 4.) On the girders 35 the carriers 33 are fastened by means ofthe flanges 34 (Fig. 4-5). To each of the carriers 33 a bracket or lug36 are fastened. Every bracket or lug is provided with a slot 85. In therollers is fastened a screw bolt 38, which is introduced in the slot 85.To each of the girders 35 a bracket or lug 37 is fastened. Every bracketis provided with a slot 86. In each of the lower rollers 8 a screw bolt39 is fastened, which is introduced in the slot 86. In said manner therollers 8, 18 are alternately connected with one of the two girders 35.

In Fig. 3 the lines 40, 40 indicate the ends of the lower roller of thefirst pair of mangling rollers and the lines 41, 41 the ends ofappertaining upper rollers; the lines 42, 42 indicate the ends of thelower roller of the other pair of mangling rollers and the lines 43-, 43theends of the appertaining upper roller.

The displacement of the girders 35 in the direction of the arrows 44makes it possible to treat with the mangling rollers fabrics per part ofthe box 1. vThese transverse of different breadth, but the breadth ofthe fabric must not exceed twice the length of the mangling rollershowever.

Referring now to Figs. 6 to 4'5, 45 is the stretchlng-frame of themercerization machines'ervmg as guide for the clamping chains 49, 49C.The chains 5L9, {L V-engage the ga e with the two bevel wheels 67, 67;The E two sprocket wheels 51, 51, are rigidly c011 nected with the bevelwheels 67, 67 so that they rotate with the same and thus move the chainin the direction ofthe arrows 68-, 68.

The chains 49, 49. consist of the links (Fig. 105) which are connectedby means of the pins 75. 'Each link of the chainis provided at 76 with aweighted lever 7 7 the end of which presses the fabric at'70 against theclearly shown in Fi 11. v

As at the in-coming end of the machine,

part 78 andthus frnil'y holds the same,ras:f'

2112. at 72', the distance between the two I chain s49, 4:9 is less thanatthe out-going end, '2'. e. at 73, the fabric will be stretched in fbreadth when it passes through the stretchling frame of themercerization machine in the direction of the arrows 68, 68". i r

p The mode of operation'of the apparatus according to the presentinvention is as follows :When the fabric 2 passes through I thereceptacle 1 in the direction of the arrows 68, 68 (Fig. 7) steam isdirected by the steam-jet pipes 24-, 25 and 27 28 against both sides ofthe fabric. At the same time the fabric is stretched in breadth bythechains 49, 49C On account of the action of *the steam the soda-lye isdiluted and at the same timeheated to such a'high temperature that thefabric is able to leave the stretching frame without shrinking. Owing tothe fabricbeing stretched in breadth the steam can more easily penetratethe fabric and remove thelye. The'condensed water collects with the lyeat the bottom of the receptacle 1 and canthen be removed from the samefor the purpose of being further treated. The pair of the ma'nglingrollers 8, 1 8 may be displaced one toward the other in the direction oftheir axis according to the breadth of the fabric to be treated,

For this purpose the 'girders mustbe' -pla''edi n the sl'ots i82indirection of'the arrows 83, 85L (Fig. 2 and Fig. ifwith the nu-anglingreliefs being 'connected with them.
